To all whom i? may concern:

Be it liner/n that JOI-1n EDWARD BAKER, a citizen e117' the UnitedStates, residing at fiend Springs, in the county o Tulsa and State o'Oklahoma, have invented certain new. 'arid risei'ni lmprovements inAnticreeping'lericcs for Track-Rails; and do declare the following` tobe a full, clear, and exact description of the invention, such as' willenable others skilled in the art to which it appar :i malte and use thesaine, referer .c had to the accompanying drawi1,. A1d to the lettersand figures ot retcrenee marked thereon, which forni a part of 'thisspecification.

lily invention relates to an anti-creeping dei-'ice for track railsandmore particularly to a device for use on rails ieading to or from atrack scale, the. principal object oi". the inrent `n beine` to preventcreeping ot' the rail: o a scale pit and resultant inter- 'c ence a 1ththe scale.

ln acooniplishiney this object have provided improved details ofstructure, the

preferred 'forros of which are illustrated in.

l-'ieferring more in detail 'to the drawings, and first to the mountingof the track rails and their combination with the scale pit andplatform, l designates a concrete pit wall., 2 track ties for supportinga ground rail, 3 a ground rail supported on the ties and attachedthereto by the spikes 4, 5 a scale platform and (S a track rail carriedby the platform in alinenient with the ground raii 3. the track andground railszheing spaced 'to provide 'for free vertical more nient ofthe platform rail. 'i

While essential that the trackand rammen' ieee. te, tera erial No. ll.

'platform rails be located in as close relation as possible in order tolimitthe break between the ends thereof, it is apparent thatlongitudinal morcrncntof either of .the rails might project the end ofthe -railover one of the movable parts to an extent thatinight interferewith cir-.preventth'e operation of the platform.l It is Well known thatsnclr device, which is so located; with respect to the scale as topermit expansion-or .creeping away from the pitand prevent like actionin the direction of the pit. The device for accomplishing this pnrposecomprises' thel chair `block 8, .having upstanding edge flanges.9za11dan pstandin g intermcdiateirail scatl() iformingl doiynr i seijaw seats 11 at opposite sidessofthe rail seat 10, the edge flangesbeingfspaedto Ereceive the base of a track rail therebctiireen andtapered on their innerfacesltoform a wedge like opening lfortliefphrpose pre s-` entlir described l The bottom ofthe chair hloclr isprovided witli`\ the tapered rib 12,.,having a l 1eel 1:3 at the frontend of the c'hzi-irflor abutment against pit wall or other ,oh st1j-notion.y The flange 9 ofthe chair block are v spaced a greaterdistance vthan the width ofj thefrail seat, so that`rhe`edges oftherailhasecmay overlie the jaiv seatsl 1 1; tolle egagedfh'y the jaws 15which are adapted Jfor-'location i i within 'the seats. Each ofthe ,j anis. is tapered at its outer Iside correspondinglyE-.to

the taper of the inner*edges ofthe anges' 9 to locate the taperedinnecedges ofthe said jaws parallel with eaoli'other, and with g theedges of the track rail, -the innenedges of the jaws being provided with.tcetl1 l'i' which are adapted for grippingthe; edges of the railhase,`so that when .the rail fis seated in thechair with the edges'ofthd base in engagement with the -j airs, moiremcnt ot the rail towardthe front of the chair will induce ognppmg action of the iid 4'55.:.While ,.Iheve described the device in jaws thereon will tend tocarrjythe j mrs along with the rails until such movement 1s prevented by thewedging of the jews against 'the-choir flanges. 7

In order to .fipport the choir on e treclr. rail andrctsiin the grippingjaws in their seats, provide .keeper plates 19, which :ire adapted forseeding;` on the upper of the flanges 9 finti for attachment thereto bycap screwe which pass through the keeper {plates into the lapertures 21in the chair 'ano'es to firmly attach the keeper plates to die flangesand eect a support of thc device on fthe track rail, the plates 19 extenling inwardly beyond the edges of the anges to overlie the .jaws andIdie edges of the ruil base to mount the dei/ice on the rail and confinethe jews.

In using the device, assuming the seme to be oonetriioted :is described,and assuming the use inl connection with n pletllori'n seele, .u seat Swith ythe jaws in their seats ll, is mounted on the bese of the groundnil by 'the keeper plates as described.Y end the end of the chair withits heel 13 moved against the outer face of the pit Wall l to form nnabutment for the ehn-ir that wili prevent :my material movement thereofin the direction of the pit.

With the device so located, the nre driven to close Contact with theedges of the track rail base and with the inner wells of the chairflanges S. i/Vith the parte so arranged, should there be any tendency ofthe ruil to creep in the direct-ion of the pit, movement of the railtoward the pit will Lend to drive the jews 15 in the saine direc-..tion. This movement is, however, resisted by the tapered Wells of thesent rniis, the induction being that of a Wedge :rnd the gripping.tendency increasing with any incre-ese in movement of the rail in thedirect-ionv of the pit, the gripping of the rail by'the jui-vs beinginduced by the abutment of the sent at against the pit Well which takesthe creepinU thrust of the rail through the seat 8. Wlhilermovement ofthe rail in the direction of the pit is prevented by the devicenedescribed, its movement in the other direction is `not interferedwith, 'iis'isuch movement ewold tend to pull .the jews away from theirseats and loosen the same in the chair, there- .by obvieting anyinterference with naturel :expansion and lcontraction of the ruil.
